In the century following the Prophet Muhammad’s death, the Islamic community expanded rapidly. With new territories came immense wealth and political complexity. Amid this growing worldliness, some devout individuals felt a spiritual disconnect. They worried that the internal, transformative essence of the faith was being overshadowed by external power and material gain.

This concern gave rise to an early spiritual movement known as Zuhd. More than simple asceticism, Zuhd was a conscious turn away from worldly distractions to focus entirely on the inner life and one's relationship with God. It wasn't about rejecting the world, but about freeing the heart from attachment to it. These early ascetics, or zahids, sought to preserve the spiritual purity they saw in the Prophet's own life and the example of his closest companions.

The city of Basra, in modern-day Iraq, became a major center for this new spiritual focus. It was a bustling hub of trade and intellectual life, making the call to inner reflection all the more potent. The leading voice of this movement was a man named Hasan al-Basri (d. 728 CE).

Hasan was a towering intellectual figure, renowned for his eloquence and uncompromising piety. He taught that true wealth was contentment and that a believer should live in this world as if a stranger, with their heart set on the hereafter. His teachings weren't about creating complex mystical theories; they were a practical, urgent call back to the core principles of the Sunnah, the normative example of the Prophet.

While Hasan al-Basri's school emphasized awe and reverence for God, another powerful idea was emerging from the same tradition: Divine Love, or Mahabba. The most famous early exponent of this concept was a woman from Basra named Rabia al-Adawiyya (d. 801 CE).

Rabia shifted the focus of asceticism. For her, devotion wasn't driven by fear of hellfire or desire for paradise. It was motivated purely by love for God Himself. She famously prayed:

This introduction of selfless, unconditional love was a revolutionary step. It moved the spiritual path from mere renunciation (Zuhd) toward a more intimate, relational spirituality. This new emphasis on the internal experience of love laid the groundwork for Tasawwuf, the term that would later be used for the disciplined, mystical path of Sufism.

Let's check your understanding of these foundational concepts.

These early figures weren't trying to create a new branch of Islam. They were trying to preserve its heart. Their discipline and focus on the inner life established an ethical and spiritual framework that would influence Islamic thought for centuries to come.
